How do I undo a Mac update without Time Machine?

The best way to undo a Mac update without Time Machine is to use an app called macOS Reinstaller. This app allows you to restore your system to its previous state by reinstalling the operating system and any installed applications.

This process requires a bootable installer, which can be created from the App Store or from the recovery partition. To create a bootable installer from the App Store, open the App Store and search for “macOS Reinstaller”.

Once the app is installed, you will be presented with a number of options to choose from. Select the version of the operating system that you would like to reinstall and click on “Create Installer”. Once the installer has been created, restart your system and boot from the installer.

The app will guide you through the process of restoring your Mac to its previous state, undoing the Mac update in the process.

Can you roll back a macOS update?

Yes, you can roll back a macOS update. While the process is complicated and can be risky, Apple does allow users to go back to a prior macOS version. It is not officially recommended, and users should understand that some programs and features may not work correctly if you do go through with the rollback.

The first step is to determine which version you want to revert to and create a backup of your data. Then you need to disable System Integrity Protection, which can be done by restarting your Mac and holding down Command + R to enter Recovery Mode, then going to the Utilities menu to open the Terminal, typing in ‘csrutil disable’ and restarting.

Next, download the macOS install package for the prior version you want to downgrade to. It must match the same type of install package that your Mac originally came with, such as ‘InstallESD’. Once the file is downloaded, double-click it to open the installer and mount the image.

Finally, use the Command/R key combination to restart your Mac and enter Recovery Mode, go to Disk Utility and erase the drive, then use the macOS installer to perform a new installation. Once the installation is complete and you’ve restarted your Mac, you can go back into Recovery Mode, re-enable ‘System Integrity Protection’ in the Terminal app and restart again.

Remember to create a backup of your files before you attempt any downgrade process. In some cases, Apple may prevent downgrading as a way of encouraging users to remain on the latest version of macOS.
